Terminal PIN
► 1 1 or 5 23 (A)

Note
If the meter is the last device on the bus, it has to be terminated at connection block 23 and 24 with a
resistor (120 ohm / 0.25W).
Note
The Inepro PRO1 Mod cannot be connected to the inverters with a single bus.
For this reason, use one RS485 connection for the inverters and one RS485 connection for the So-
lar-Log™ PRO1 Mod.
► A combination with a M&T sensor as well as with the Solar-Log™ PRO380 Mod and Solar-Log™
Pro380-CT in the same bus is possible.
